When to Consider Solar Water Heater Installation

Are you building a new home in Hawaii?

State law requires most new single-family homes in Hawaii to include a solar water heater system unless a variance is approved. If you’re building, Steve’s Plumbing & A/C can design and install a code-compliant system from the start, so there’s nothing to revisit later.

Is your current water heater driving up your electric bill?

Water heating is one of the largest energy costs in a Hawaii home. If your electric bill feels high or your current tank is aging, switching to solar can significantly lower your monthly costs while reducing strain on an older system.

Does your roof get good sun exposure?

Homes with roof space that receives several hours of direct sunlight each day are excellent candidates for solar. Steve’s Plumbing & A/C can assess your roof and recommend the right collector type and placement for your property.

No matter which island you live on or the size of your home, we’ll design a solar water heater system that fits and make sure it’s installed right the first time.

Solar Water Heater Service In Hawaii FAQs​

Rooftop collectors absorb heat from the sun and transfer it to water or a heat-transfer fluid, which is then stored in an insulated tank. A controller manages the system automatically, and a backup heater, electric or gas, keeps water hot whenever the sun can’t keep up.
Yes. Every solar water heater we install includes a backup heating element. If the tank temperature drops below a set point, the backup switches on automatically, so your household never runs out of hot water regardless of the weather.
Solar water heaters can reduce water heating costs by up to 80 percent compared to a standard electric tank. Given Hawaii’s high electricity rates, most homeowners see the system pay for itself within 7 to 10 years through energy savings alone.
Under Hawaii Revised Statutes Section 196-6.5, new single-family homes must include a solar water heater system before a building permit is issued, unless the homeowner obtains an approved variance. Steve’s Plumbing & A/C installs code-compliant systems for new construction across the state.
It depends on your roof. Solar water heaters work best on roofs with strong, consistent sun exposure and offer the highest energy savings. Heat pump water heaters are a better fit for homes with limited or shaded roof space, and they cost less upfront. A Steve’s technician can help you weigh both options against your roof, budget, and energy goals.
